PRINTING--MAOI-IINE.

Application filed August 11, 1917.

To all whom it may concern Be it known that I, ANTHONY S. Busir, a citizen of the United States, residing at il oodhaven, county of Queens, and State of New York, have invented certain new and useful Improvements in Pi'inting-h iachines, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to certain improvements in printing machines, and particularly that class of printing machines wherein a sheet, after it has been printed, may be scored or cut and delivered from the machine, and the invention has for its especial object the provision of an improved mechanism. for driving the scoring or cutting device so that it may cooperate with the printing mechanism to out or score a sheet after it has been printed, or, where such scoring or cutting is not desired, the cutting or scoring mechanism may be silenced without interrupting the operation of the printing mechanism, so that the latter may operate in the usual manner.

Another object of the invention is to provide a driving mechanism of simple form for effecting the principal object of the invention, the mechanism of which is readily accessible and easily controlled and operated.

With these and other objects in view, the invention consists in certain novel parts and combinations which will be described in connection with the accompanying draw ings, in which Figure 1 is a side elevation of a printing machine showing a cutting and scoring mechanism in operative relation therewith;

Fig. 2 is a plan view, partly in section and partly broken away, on the line 22 of Fig. 1; and

Fig. 3 is an end elevation, partly in section and partly broken away, of part of the machine shown in Fig. 1, Figs. 2 and 3 illus trating in detail and on an enlarged scale the improved driving mechanism.

Referring now to these drawings in detail, the machine chosen to illustrate the in vention is a sheet fed rotary machine in which the sheets are fed from a pile and in which the printing elements are cylinders adapted to print a plurality of colors on a sheet, but it will be understood that i Specification of Letters Eatent.

Patented May 4, 1920.

Serial No. 185,677.

the invention is applicable to other types of machines in which sheets may be fed from other sources of: supply than a pile and in which all the printing elements are not cylinders.

Referring to the particularmachine illustrated the various mechanisms are supported in suitable frames 1, which may be of any usual or desired construction and configuration.

The particular machine shown is arranged to print four or less colors and to cut or score the sheet during its travel through the machine. The forms, which may be of any suitable type, are carried by form cylinders 2, 3, 4L and 5, inked by the usual inking mechanism and arranged to successively print on a sheet, these form cylinders being suitably mounted in the frames 1 before referred to. These form cylinders cooperate with an impression member which, in the particular machine illustrated, is a large impression cylinder 6 provided with suitable sheet taking devices, such devices, inthe present instance, being grippers 7, these grippers being operated in the usual manner to take sheets which are fed thereto from a feed board. 8, the impression cylinder and feed board-being suitably mounted in the frames 1.

In machines constructed in accordance with the invention, there will be provided a cutting or scoring mechanism by which the sheets, after printing, may be cut or scored prior to their delivery from the machine. This cutting or scoring mechanism may vary somewhat in construction, but will include a pair of cooperating members, one of which will carry the cutting or scoring devices, and the other of which will act as an abutment against which the cutting or scoring is effected, and in machines embodying the invention in its best form, the cutopposite the clutch face sired to operate the machine as a straight printing machine, without the cutting or scoring devices operating, it will be found convenient to employ a partof the delivery mechanism to effect the function of this cooperating member. In the particular machine illustrated, therefore, a delivery cylinder 11, suitably mounted in the frame 1 of the machine is provided, this cylinder be; ing provided with sheet taking devices, such as grippers 12 for holding the sheet thereon while it is cut or scored against the cutting or scoring form 9, the cylinder 11 thus acting as an abutment against which the cutting or scoring is effected. This delivery cylinder 11, whetherthe machine is used with a cutter or scorer in operation or not, may deliver the sl'ieets from the machine to any suitable final. deliver, as tapes 13.

The sheets are presented to this delivery cylinder from the printing elements in any suitable manner. In the particular construction illustrated, there is provided a transfer cylinder 14 provided with sheet taking devices, as grippers 15, which take the sheets when they are released by the grippers 7 of the impression cylinder and transfer them to the sheet taking devices 12 of the delivery cylinder 11. T his construc tion is preferable, as the sheet is under positive gripper control during its passage through the machine. I

in machines constructed in accordance with the invention, a drivingmechanism is provided whereby the printu and delivery cylinders the bed, when the scoring form support is a bed, may be driven from a single source of power, or the bed may be silenced without interruptingthe printing and delivery mechanism, so that the press, if desired, can be o n-irated without the cutter or scorer. The iiarticular cwistruction for effecting this mz-iy be soi'ucwhat varied, but'in the r rticular construction illustrated there is provided moulded in the a of the machine, this shaft carryin at one end. a pulley 17 di'ven by belt 18 from a pulley 19 on the shaft of a motor, indicated generally by the numeral 20. The power shaft 16 has at one the gear being gt revented by a collar 23'. in

which can be slid in and out of engagement with the clutch 'ear 22., hereinafter rcferred'to. The face of the clutch gear 22, is formed with afihubo'r extension 25, to'which. is secured, so asto rotate therewith, as by a key26, a

27, which gear'is 'in' mesh with an intermedlate gear 28, whlc'lrinturn meshes a ower s aft 16 suitably l ast on the shaft 23 is a clutch member 24' the clutch is necessary.

with a gear 29 on the delivery cylinder 11, before referred to, this gear 29 meshing with a gear 3 on in turn meshes with a gear 31 on the impression cylinder 6, these cylinders being thus driven. c

'1. he bedll), on which is carried the cutting or creasing form 5 before referred to, is mounted to be reciprocate-d beneath the delivery cylinder 11 in suitable guides rising'from the bed of the machine, The reciprocation of the bed may oe effected in any desired. manner and through. various constructions. in the particular construe. tion illustrated this is effectec by means of a rack 33 extending from a'bracket 34' secured to the underside of the bed and mounted to slide in guide 35 secured to the frame of the machine. This rack. is reciprocated in the particular construction shown by means of a spur gear 36 carried on one end of a shaft 37 pivotally'cennected at through a coupling 3- to the inner end of the driven shaft 23, before referred to. lVhenit is dcsired'to operate the bed, the clutch member 24c, which, as before stated,

is mounted fast on the driven shaft 23, is V thrown into engagement with the clutch member 22? of the clutch gear 22, thereby locking this gear to the shaft 23 and causmg the shaft 23 and theshaft 37 to rotate. The

. mesh with the rack whenit is dropped to the underside thereof. If desired, a bearer may be provided,moving with therack, with which cooperates a flange li on the outer face of the gear 36,-this bearer and flange taking'the weight of the gear off the rack when the gear is in the upper position, as shown in Fig. 3. Y

It will be seen from the foregoing that a simple construction has been provided whereby a sheet fed press may be provided 'with a cutting or scoring mechanism which can be driven from the same source of power as the printing elements of the machine, but which cutting or scoring mechanism may be silenced without interrupting or otherwise disarranging' the operation of the printing elements of the machine, thus effecting a verycompaictstructure in which the transfer cylinder 14:, which no adiustment other than the throwing of 7 'It will be understood that various changes may be made in the specific construction of .tel.heuzestrictedtothe prejcis v. ,jdriving ethe? couple,".rconnections from. the
